The invention discloses a traffic signal timing optimization method based on an improved crown porcupine algorithm. The method comprises the following steps: 1) collecting information of a traffic signal intersection; 2) establishing a traffic signal timing optimization model of the intersection; 3) setting constraint conditions of the traffic signal timing optimization model; and 4) converting a multi-objective optimization problem of the intersection traffic signal timing optimization model into a single-objective optimization problem, and performing model solution in combination with model constraints to obtain a traffic signal timing scheme of the intersection in the current period. According to the traffic signal timing optimization method, the improved crown porcupine algorithm is used for solving the objective function, the optimal solution is obtained through optimization, and the feasibility and the excellence of the intersection signal timing scheme can be effectively improved.
